thorns_nz Posted July 13, 2011 Posted July 13, 2011 Hi, Just hoping to get some help for the problem I'm having making my thread using the coil function. I have drawn the profile of the thread on the shaft part that is needed. However I cant get it to end properly, I need it to blend into a flat edge at both ends of it, however I am unsure how to do this. I have attached a photo of the part I am trying to create, and a screen shot of what I have in Inventor. I drew the sketch of the thread in the center and was hoping to run it 3" in each direction. I have been using the coil feature to try do this, is this the correct feature tool to use? Hopefuly you can see from the photos what I am trying to do, in case my explanation isn't all that clear.

Pablo Ferral Posted July 14, 2011 Posted July 14, 2011 You might get this by playing with the coil's end conditions. Otherwise, you could create a start and finish plane and use them to slice away the portion of the coil that you don't want. Quote
thorns_nz Posted July 14, 2011 Author Posted July 14, 2011 Thanks for that Pablo. I had a similair thought in the car on the way home. Was thinking that if I extend the thread further than the 3" needed in each direction, and then create a 'cut' extrusion from each end to finish 3" from the center this should work. Perhaps not the proper way to do, but I think it should work. Is that similar to what your were thinking? I had a play with the options for the end condition, but it did'nt seem to achieve what I was after. Would love to know if there is a simple way to do this properly. Thanks. Quote
JD Mather Posted July 14, 2011 Posted July 14, 2011 Why don't you use frame generator? What does this have to do with the question asked - can you post an example solution using the Frame Generator. Quote

(coil end conditions will not be the solution) Quote

Tried attaching a zip file with the part, but wrk has uploading screwed down pretty tight it seems. Quote
